Patented Jan. 13, 1931 mnnonon PAUL monies, ornntnn'enirgfennmaiw LEAD-PENCIL snnarnnnn WITH eAsE-g Application fled September 28, 1929, Serial No.i395,916',=and in Germany A fii 1e, 1929 The subject of this invention is a lead pencil sharpener, in which a case with a hinged lid is provided for accommodating the wood shavings and pencil dust produced in sharpening and in which the sharpening device is carried by the lid and adapted to be concealed or exposed according to the position thereof. Sharpening devices of this kind have the'advantage that the waste materials can be stored in the closed case until opportunity arises to empty same. The pencil sharpener is therefore particularly suitable: for instances when the lead pencil has to be sharpened and there is no immediate opportunity for discarding the waste, such as in a dish,

waste paper basket, &c. The invention enables thesharpening device and the hinged lid of the metal'case to be held by catch means, in such position that the pencil canbe 'sharpened while the case remains closed'to the escape of the shavings. 1 7

Two typical embodiments of the invention are illustrated in the drawing, in which Figure 1 represents a longitudinal section through oneform, with the lid closed; Figure 2 is a longitudinal section corresponding to Figure 1 but with the lidopen and the V sharpener in position for use; Figure 3 is a view partly in cross section and partly in elevation taken on line 33 of Figure 1, and Figure 4 is a perspective view of a second embodiment with the sharpener inposition for use.

Referring first to the form of Figures 1 to 3, a lead pencil sharpener 1, of taper design is attached (preferably by means of one or more screws) to a hinged lid 2, hinged at 10 to a box-shaped or rectangular case 3. The rear part of the lid 2 carries a-fill et 4, of quadrangular cross section, whose outer surface forms part of the outer surfaceof the case when the lid is closed. Attached to the lid 2, at one side of the sharpener 1, is a catch bar 6, having a projection 7 which engages in a socket or recess 8 in the wall of the case when the lid is open or turned into the is no' immediate opportunity of discharging the contained waste, the'lid 2 is closed, and

The case is emptied in t e same manner as in the first embodiment,'by turn- 7 ing the lid back until said plates arespaced from the case. i 1
